TECHNICAL FIELD

The present disclosure relates to the field of optical lens, and moreparticularly, to a camera optical lens suitable for handheld terminaldevices such as smart phones or digital cameras and camera devices suchas monitors or PC lenses.

BACKGROUND

With the emergence of smart phones in recent years, the demand forminiature camera lens is increasing day by day, but in general thephotosensitive devices of camera lens are nothing more than ChargeCoupled Device (CCD) or Complementary Metal-Oxide Semiconductor Sensor(CMOS sensor), and as the progress of the semiconductor manufacturingtechnology makes the pixel size of the photosensitive devices becomesmaller, plus the current development trend of electronic productstowards better functions and thinner and smaller dimensions, miniaturecamera lenses with good imaging quality therefore have become amainstream in the market.

In order to obtain better imaging quality, the lens that istraditionally equipped in mobile phone cameras adopts a three-piece orfour-piece lens structure. Also, with the development of technology andthe increase of the diverse demands of users, and as the pixel area ofphotosensitive devices is becoming smaller and smaller and therequirement of the system on the imaging quality is improvingconstantly, a five-piece lens structure gradually appears in lensdesigns. Although the common five-piece lens has good opticalperformance, its settings on refractive power, lens spacing and lensshape still have some irrationality, which results in that the lensstructure cannot achieve a high optical performance while satisfyingdesign requirements for wide-angle and ultra-thin lenses having a bigaperture.

DESCRIPTION OF EMBODIMENTS

The present disclosure will hereinafter be described in detail withreference to several exemplary embodiments. To make the technicalproblems to be solved, technical solutions and beneficial effects of thepresent disclosure more apparent, the present disclosure is described infurther detail together with the figure and the embodiments. It shouldbe understood the specific embodiments described hereby is only toexplain the disclosure, not intended to limit the disclosure.

Embodiment 1

Referring to FIG. 1, the present disclosure provides a camera opticallens 10. FIG. 1 shows the camera optical lens 10 according to Embodiment1 of the present disclosure. The camera optical lens 10 includes 5lenses. Specifically, the camera optical lens 10 includes, from anobject side to an image side, an aperture S1, a first lens L1, a secondlens L2, a third lens L3, a fourth lens L4 and a fifth lens L5. Anoptical element such as a glass plate GF can be arranged between thefifth lens L5 and an image plane Si. The glass plate GF can be a glasscover plate or an optical filter. In other embodiments, the glass plateGF can be arranged at other positions.

In present embodiment, the first lens L1 has a positive refractivepower, and has an object side surface being a convex surface and animage object surface being a concave surface; the second lens L2 has anegative refractive power, and has an object side surface being aconcave surface and an image object surface being a concave surface; thethird lens L3 has a positive refractive power, and has an object sidesurface being a convex surface and an image object surface being aconcave surface; the fourth lens L4 has a positive refractive power, andhas an object side surface being a concave surface and an image objectsurface being a convex surface; and the fifth lens L5 has a negativerefractive power, and has an object side surface being a convex surfaceand an image object surface being a concave surface.

Here, a focal length of the camera optical lens 10 is defined as f in aunit of millimeter (mm), a focal length of the first lens is defined asf1, a focal length of the third lens L3 is defined as f3, a curvatureradius of the object side surface of the third lens is defined as R5,and a curvature radius of the image side surface of the third lens isdefined as R6, where f, f1, f3, R5 and R6 should satisfy followingconditions:

0.80≤f1/f≤0.90  (1);

70.00≤f3/f≤120.00  (2); and

−450.00≤(R5+R6)/(R5−R6)≤−430.00  (3).

The condition (1) specifies a ratio of the focal length of the firstlens L1 and the focal length of the camera optical lens 10. This leadsto the appropriate distribution of the refractive power for the firstlens L1, thereby facilitating correction of aberrations of the cameraoptical lens and thus improving the imaging quality.

The condition (2) specifies a ratio of the focal length of the thirdlens L3 and the focal length of the camera optical lens 10. This leadsto the appropriate distribution of the refractive power for the thirdlens L3, thereby facilitating correction of aberrations of the cameraoptical lens and thus improving the imaging quality.

The condition (3) specifies a shape of the third lens L3. This caneffectively correct aberrations generated by first two lenses (the firstlens L1 and the second lens L2) in the camera optical lens.

In this embodiment, with the above configurations of the lensesincluding respective lenses having different refractive powers, in whichthere is a specific relationship between the focal length of the cameraoptical lens 10 and the first lens L1, there is a specific relationshipbetween the focal length of the camera optical lens 10 and the thirdlens L3 and the third lens L3 has a specific shape, this leads to theappropriate distribution of the refractive power of the first lens L1and the refractive power of the third lens L3, thereby facilitatingcorrection of aberrations of the camera optical lens. This can achieve ahigh optical performance while satisfying design requirements forwide-angle and ultra-thin lenses having a big aperture.

In an example, a curvature radius of the object side surface of thefirst lens L1 is defined as R1 and a curvature radius of the image sidesurface of the first lens L1 is defined as R2, where R1 and R2 satisfy acondition of:

−1.50≤(R1+R2)/(R1−R2)≤−1.35  (4).

The condition (4) specifies a shape of the first lens L1. Within thisrange, a development towards wide-angle lenses having a big aperture canalleviate a deflection degree of light passing through the lens, therebyeffectively reducing aberrations.

In an example, a curvature radius of the object side surface of thesecond lens L2 is defined as R3, and R3 and f satisfy a condition of:

−10.70≤R3/f≤−9.50  (5).

The condition (5) specifies a ratio of the curvature radius of theobject side surface of the second lens L2 and the focal length of thecamera optical lens 10. This can facilitate processing and assembly ofthe lenses.

In addition, a surface of a lens can be set as an aspherical surface.The aspherical surface can be easily formed into a shape other than thespherical surface, so that more control variables can be obtained toreduce the aberration, thereby reducing the number of lenses and thuseffectively reducing a total length of the camera optical lens accordingto the present disclosure. In an embodiment of the present disclosure,both an object side surface and an image side surface of each lens areaspherical surfaces.

It should be noted that the first lens L1, the second lens L2, the thirdlens L3, the fourth lens L4 and the fifth lens L5 that constitute thecamera optical lens 10 of the present embodiment have the structure andparameter relationships as described above, and therefore, the cameraoptical lens 10 can reasonably distribute the refractive power, thesurface shape, the on-axis thickness and the like of each lens, and thuscorrect various aberrations. The camera optical lens 10 has Fno ≤2.05. Atotal optical length from the object side surface of the first lens toan image plane of the camera optical lens along an optic axis (TTL) andan image height (IH) of the camera optical lens 10 satisfy a conditionof TTL/IH≤1.50. The field of view (FOV) of the camera optical lens 10satisfies FOV≥76.9 degrees. This can achieve a high optical performancewhile satisfying design requirements for wide-angle and ultra-thinlenses having a big aperture.

In an example, inflexion points and/or arrest points can be arranged onthe object side surface and/or image side surface of the lens, so as tosatisfy the demand for the high quality imaging. The description belowcan be referred to for specific implementations.
